Like any other movie in the interlocking Marvel Cinematic Universe, Thor: Ragnarok had some work to do during and at the end of its closing credits to set up future installments in the franchise. Thought not as crazy as the five scenes peppered throughout the end of Guardians of the Galaxy Vol. 2, a pair of short moments hinted at the destruction and potential team-ups to come in 2018’s Avengers: Infinity War.

In fact, Thor: Ragnarok got off easy. Though fans once expected this film to have to do a lot of heavy lifting when it came to the overarching story Marvel is trying to tell, director Taika Waititi skated by with very minimal set-up. But if set-up is your thing, then here’s a deeper dive into what was going on with Thor and the rest as the credits rolled. Spoilers follow, obviously.

When Ragnarok ends, Thor, Loki, Heimdall, Valkyrie, and a group of displaced Asgardians are in a ship on their way to make a new home on Midgard, a.k.a. Earth. (We’d guess Thor has that grassy Norwegian cliff where Odin made his last stand in mind.) In the first, brief end-of-credits scene, Loki expresses some doubts about how Earthlings might treat him after he, you know, tried to destroy them all in 2012’s The Avengers. But on the whole, the brothers have reached a nice, tentative truce as they cruise into space.

Just then, a massive, ominous spaceship looms into view. If you’ve been paying attention at all to the Marvel Cinematic Universe, you don’t really need me to tell you that this ship belongs to the big purple bad threatening to tear the world apart in Avengers 3 and 4: Josh Brolin’s Thanos. The ship is similar in design to the bug-like one that invaded New York at the end of the first Avengers movie, which means that it’s likely filled with Thanos’s allies: the aliens knows as the Chitauri. Thanos, Loki, and the Chitauri all conspired together to try to destroy Earth in that film. Not only did Loki fail, but now he’s working with the good guys. How well do we think Thanos will take that news?

Loki also has something that Thanos wants. If you’ve been following the chatter around these movies and the long buildup to Thanos’s arrival (Marvel started teasing the purple menace in post-credits scenes 12 movies ago!), then you might be familiar with the Infinity Stones. Thanos has a powerful golden Infinity Gauntlet (or glove); as Hela points out in Ragnarok, the gauntlet sitting in Odin’s vault is a fake. If you look closely at the image above, you’ll see an empty spot on each knuckle. That’s where the Infinity Stones we’ve seen spread out over the past several films will likely wind up. We’ve seen one in Guardians of the Galaxy—the Power Stone, a.k.a. that purple thing that threatened to rip Star-Lord and his gang apart. Loki got very familiar with one in The Avengers—the Mind Stone, a.k.a. the one embedded at the end of the scepter he used to stab and (temporarily) kill poor Agent Coulson. You remember.

The Mind Stone is currently lodged in the forehead of Paul Bettany’s android character, Vision. There are a few more stones spread around—but most salient to our end-of-credits discussion here is the Space Stone, a.k.a. the blowing, glowing cube also known as the Tesseract. Loki also used this stone in The Avengers to rip open an inter-dimensional hole and let the wrong ones (a.k.a. the Chitauri) in during the Battle of New York. The Tesseract was also in Odin’s vault, and caught not only Hela’s eye, but also Loki’s. We can bet he grabbed it on his way out the crumbling Asgardian door and has it tucked away on that ship.

Much ado about the Infinity Gauntlet and Infinity Stones will finally come to a head in the next Avengers film, titled, unsurprisingly, Infinity War. That film’s co-director, Anthony Russo, told io9 the massive cross-over event is a heist movie centered on Thanos’s pursuit of those stones:

With Infinity War, the biggest new element to the movie is Thanos and the fact that he’s entering the storytelling in a very bold, strong way, to the degree that he’s almost one of the leads. We’ve shaped an interesting narrative around him that in some ways leans heavily on a heist film in the fact that he’s going after the Infinity Stones in a much bolder, successful way than he has in the past. The entire movie has that energy of the bad guy being one step ahead of the heroes. We looked at a lot of movies that had that heist-style energy to them, [and] that brought some inspiration.

The first casualty in that war/heist might be Thor’s ship. The Infinity War footage Marvel showed at D23 this year seemed to pick up just after this end-of-credits scene, with Star-Lord and his fellow Guardians of the Galaxy gazing at the wreckage of a space battle. “This could be dangerous,” their leader says, “so everyone put on your mean faces.” Just then, Thor lands with a smacking thud on the Milano’s windshield. The Guardians bring the beaten and unconscious Thor onboard, where the empathic Mantis wakes him up. Angry and upset, Thor demands to know “who the hell are you guys?!” In later footage, he intones to his newfound space friends that “something’s very wrong.” There was also a shot in that footage of Loki handing the Tesseract up and out to someone much taller than him. Either he’s trying to wield it against Thanos or he’s trying to buy himself back into his old boss’s good graces. With Loki, you truly never know.

The final end scene, featuring Jeff Goldblum’s Grandmaster, seems like a simple comedy moment—the perfect whimsical button to this zany movie. But Marvel has made it clear that we’ve likely not seen the last of this Goldblum character. In an interview with Fandango, Marvel Studios head Kevin Feige hinted at a future collaboration between the Grandmaster and his brother, Benicio Del Toro’s Collector (last seen in Guardians of the Galaxy):

If you go on the Guardians of the Galaxy: Mission Breakout attraction at California Adventure in Anaheim, you will see a picture on Collector’s wall of he and the Grandmaster playing some sort of a space chess game, which right now is the only place you can see the two of them in a frame together, but let’s hope that changes someday.

That art of the two powerful Elders, together, looks like this:

You may remember that the Collector knew a lot about the Infinity Stones—he provided some handy exposition in Guardians of the Galaxy:

In the comics, Thanos grabs the stones he needs to glam and power up his gauntlet from the Elders like the Collector. In the movies, it looks like the various Avengers and Guardians will be his target. Still, I’d be surprised if the Collector and the Grandmaster sat this upcoming inter-dimensional battle out entirely.
